@delta so yeah, #deltaChat does proper #E2EE with #SelfCustody in a #decentralozed, #SelfHosting capable fashion.

• Whilst one may argue that #IMAP & #SMTP as well as #PGP/MIME were never "designed" for that, they do work reliably, don't require much cooperation (cuz even the strictest #CGNAT allows #eMail!) and can be transparently shoved through #VPN|s & @torproject / #Tor without much fuss.

Plus the "store & forward" architecture of #eMail lends itself to #AsynchronousCommunication, making it a good option when people need to "keep it brief"...

• Add to that existing technologies like "#DataMule" style units to provide almost-#airgapped communities with "high bandwith, high lantency" connections as well as #SATCOM, I'd not be surprised if delta chat would work excellent everywhere on the planet - regardless if using #Iridum in #Antarctica, 10GBit/s FTTH in Sweden or uucp in Western Sahara.
